Product Description
*CAD data currently being revised for this series. This will be available as soon as modifications are complete.
[Features]
· Supports tilted work and transport of vinyl packages.
· A wide range of pad sizes, pad materials, and holder shapes are available.
· Downsizes holders (A and B types) for existing vacuum pads, saving space.
· The pad section can be changed without removing the holder from the equipment, as is conventional.
· Also compatible with the optional fall prevention valve and pad direct attachment type filter.
· Pad holders have been added for applications requiring copper-based metal not to be used and as part of efforts to reduce ozone concentrations.
· Copper-based metal is not used for metal parts. HNBR is used for sealing rubber material.
